IPC: B23P19/04
Filed: 1991-03-18
Abstract: A fitting to provide a pouring spout at a hole through a sheet material (e.g. cartonboard) container has a flange 10 which abuts the material 44 around the hole.  A tubular portion 12 extends through the hole and tapers.  A ring 36 is dimensioned to fit on this tapered section 16 but become stretched upon pushing it up the taper towards the flange 10.

Title: Air concentrator
Inventor: PIGGOTT KEITH
IPC: C22B11/02
Filed: 1990-02-12
Abstract: An air concentrator for dry separation of gold and other heavy minerals from alluvial deposits comprises a housing (50) having a number of open-topped chambers (52) arranged in a ring-like configuration and surmounted by a screen (14) having rings (39, 41) thereon forming annular screen beds (36). A wiper bar assembly consisting of a number of wiper arms (6,7) radiating from a hub (1, 2) sweeps over the screen beds (36). Air under pressure is fed sequentially and cyclically to the chambers (52) by a rotary valve (28) located centrally of the ring of chambers. The deposit is fed over the hub (1, 2) and is swept outwardly over the beds (36) on the screen (14) by the wiper arms (6, 7), where it is fluidised by pulses of air from the subjacent chambers (52) enabling particles of gold and heavy minerals to settle down to the bottom of the beds (36) by gravitational stratification; and if sufficiently small, pass through the screen (14) for collection through spigots (38) in the bottom of the chambers (52).

Title: Method of forming electrodes for trench capacitors
Inventor: ELLUL JOSEPH P
IPC: H01L21/334
Filed: 1992-07-29
Abstract: A method is provided for forming electrodes of a trench capacitor for an integrated circuit in which the number of mask levels is reduced.  The method is compatible with CMOS and Bipolar CMOS processes.  After defining a trench in a substrate by a conventional photoengraving step and anisotropic etching, successive conformal layers of a first dielectric layer, a first conductive layer, and subsequent conformal dielectric layers and conformal conductive layers are deposited to fill the trench.  The resulting structure is planarized, preferably by chemical-mechanical polishing to provide fully planarized topography.  Each of the conductive layers form an electrode.  Coplanar areas of each of the conductive layers are exposed within the trench for formation of contacts to the electrodes.  Advantageously, the trench has a wide portion and a narrow portion of smaller lateral dimension. The narrow portion of the trench is filled by the first conductive layer and after planarization provides an area of sufficiently large dimension for forming a contact to the first electrode.  Contact to the second electrode is made in the first portion of the trench.  Thus multiple electrodes for a trench capacitor are defined by a maskless process.

The misalignment in time is due in part to a non-simultaneous transmission of the identical digitally encoded information from the plurality of transmitters.   Equalizer embodiments  include a Decision Feedback Equalizer (DFE) and an equalizer based on a Maximum Likelihood Sequence Estimator (MLSE).  Embodiments of the DFE are an Order Recursive Lattice-DFE and a Fast Kalman DFE.

Title: Unitary inflatable penile prosthesis
Inventor: BLEY ROBERT
IPC: A61F2/26
Filed: 1992-09-11
Abstract: ABSTRACT OF THE DISCLOSURE      A factory preassembled, preferably partially prefilled three piece penile prosthesis that can be implanted in a patient as one pre-assembled unit and filled without any required further connection or purging of air.  The prosthesis has a pair of inflatable cylinders that can be implanted into the corpora cavernosa regions of the penis, the inflatable cylinders preferably being attached to a solid rear portion to which the various tubing is connected.  The prosthesis also has a reservoir for implantation into the abdomen, a pump for implantation into the scrotum for transferring fluid from the reservoir into the cylinders, and a controllable valve associated with the pump for retaining the fluid within the cylinders and for controllably allowing it to escape from the cylinders back into the reservoir when desired.  When fluid is pumped into the cylinders, the cylinders are inflated to to encourage the penis to an erect position.  When the fluid is subsequently released from the cylinders, the cylinders deflate to allow the penis to return to a relaxed position.  The volume of fluid within the preoperative prosthesis assembly is such that sufficient fluid may be readily displaced from the reservoir into the pump and cylinders to allow the reservoir to be inserted into the pelvic cavity of a patient without disconnecting the pump and cylinders.  An alternate embodiment contemplates an unfilled prosthesis assembly, retaining the advantages of a preassembled unit in implantation time required and elimination of the potential for eventual connector failure.
